The assessment of ergonomic knowledge and practice among dental students and dental practitioners in Riyadh Elm University, Saudi Arabia: A cross-sectional study

Abstract

Introduction: Work-related musculoskeletal disorders (WRMSDs) represent a significant occupational hazard worldwide that impacts job satisfaction and efficiency among dental students and practitioners. This may be attributed to inadequate workplace ergonomics. Despite the numerous benefits of ergonomics, its implementation has consistently been neglected. The study aims to assess the knowledge and practices of dental ergonomics among dental students and practitioners in Riyadh Elm University (REU) Hospital, Saudi Arabia, as well as their association with demographic characteristics. Materials and Methods: This cross-sectional study consisted of 256 dental students and dentists who are currently practicing at REU Hospital, Saudi Arabia. Data on the knowledge and practices of dental ergonomics among participants were collected through a self-administered online survey from May to October 2024. Knowledge scores were categorized as good, fair, or poor, whereas practice scores were classified as either good or bad. The association of ergonomic knowledge and practice levels with demographic factors was assessed using multiple linear regression analysis. Results and Discussion: A total of 136 (53.1%) participants exhibited a good level of ergonomic knowledge, whereas just 129 (50.4%) participants demonstrated good ergonomic practices. Gender (P = 0.010) and clinical experience (P = 0.025) showed a significant association with knowledge scores, whereas age group (P = 0.045) was significantly associated with ergonomic practice scores. Conclusion: The study participants demonstrated adequate ergonomic knowledge; however, implementation into practice was lacking. Ergonomic training programs that emphasize on ergonomic education and WRMSD prevention and coping mechanisms should be integrated into the dental curriculum.
